Noteable objects in LASCO C3

Every year, on roughly the same dates, we see "famous" stars, clusters, etc, in the LASCO C3 field of view. This short list is a collection of some of the highlights. For some of the objects I have linked to images that point them out, but to find the exact locations of the others, you should check the LASCO Sky Map. Transits of planets and asteroids, which occur on different dates every year, are listed here. All dates given below are approximate (though some are more approximate than others...), and all objects enter on the left and exit on the right of the images.

This is certainly not an exhaustive list, as LASCO sees hundreds of bright stars every year. But if there's a particular star/object that you feel should be added here, please email me and I'll add it in.
